As an international TA getting accustomed to the landscape of my University, I managed to earn the ire of my instructor/professor for having not shown up during the discussion/office hours.
In a strongly worded mail, he has sought an explanation while reprimanding me saying that another instance of this would lead to serious consequences.
I am afraid that I may lose my assistantship as I curse my folly for being so careless. I have apologized to the Professor over mail but from the tone of his reply, he seems to have not considered it. Please suggest how I must handle this predicament.
